Hi,
What can make a video jerky even if the fps stay at 50 and the video time is about 1.0 ms?
I've done a test with two clusters.
The master play an empty scene and the slave play a movie when I press a key.
When the movie doesn't play the slave cluster info stay in green.
When the movie is playing the slave cluster info blinking and video is jerky.
It seems to be a bad understanding of the cluster clock by the slave or something like this...
The problem occur especially with two AMD V8800 cards without the swap sync enable. (when i enable the swap sync the cluster info stay perfectly green)
When I make the test with two Nvidia Geforce It run quiete stable even if sometime the cluster clock is lost (cluster info sometime stay gray for a few time when playing the movie).
When I mix the graphics cards perfect green cluster info is random.

Re: Loosing good cluster clock synchronisation
hi robert
are you sure, that all of your system is running on 50 fps? it is quite important, that especialy your master is running on 50 because he is generating your cluster clock...and if your client or your master is on 60....i will be jerky! and it is important that also your gui display is running on 50! otherwise the system could switch internal to 60fps!
